The Taxi Pack is an ability which Banjo learns from Jamjars in Terrydactyland inside the waterfall cave. Without Kazooie taking up space in the backpack, there is more room available for Banjo to carry larger objects, such as batteries, and that's exactly what the Taxi Pack allows him to do!

Hold and press to hold the backpack, and then while still holding press to pick objects up. Banjo can still move, jump, and attack while carrying something, but he must drop it by holding and pressing again in order to rejoin with Kazooie. The object inside the pack will not come out willingly unless its destination is reached; if for some reason Banjo wants to dump it before then, the only way to remove it is to press followed by . If not picked up again quickly, it will warp to its original location.
